ADJUSTABLE I-IANDLE fQRJ/IAQI-UNE DIES. r j

This invention relates to a die structure employed in cutting heel lifts,'soles,1 laps,

etc, in the manufacture of shoes, but more particularly to an adjustable handle for the die structure.

The cutting dies, including the handle,

therefor, now employed for the purpose referred to, are one-piece structures, that is to say solid, as the handle is integral. with i the cutter. -Al'ter the cutterbecomes dull,

it has to be ground E to sharpen the same, which makesthe CllG-Stl'LlCtlllG shorter, then furthermore the handle thereof has to be ,heated and drawn ont, but after completion thedie structures are not of uniform length or.h eight,as some are lower than 'the others,

.and. in amajority of cases to obtain the proper length or. height for the diestruc 'ture, it necessitates theemployment of a invention and to this end the invention has length of leather which is tied over the top of. the die, structure.- to increase the height of the latter, but astheleather quickly becomes worn anddoes not possessany lasting qualities for the purpose 1nt-ended it has to.

be repeatedly replaced. 'The foregoing requirements are objectionable, inthat theyen- ,tail aloss of time,.are of considerable inconvenie nce in obtaining the proper height for H the die structures ,and further increases the To overcome the fore-I cost of maintenance.

of the invention, but; it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

. In the drawings wherein like reference characters denote corresponding parts throughout the; several views:

Figure 4 is a fragmentary view, -in plan,

:,Referring to Eigures land 2 ;of thedrawings 1 denotes the body portion of thedie structure and whichis open-.at its lower end and: closed at its top, asatj2. The body portioniforms a cutter receivenand the cut- }ter-,,. which is indicated at 3,,is ,tojbe positioned within the open -end-,of ,the bodyrpor- .tion l. The top 2..of;the-body portion 1 is of greaterthic kness than the remaining part of said; body portion 1. The blody portion .1, furtherv conforms in. ,contour to the. shape going objections is the primary,aim .of this for its object to provide,,;in a manner as hereinafter set forth, a diestructure includ-L f ing asectional handle capable of, being; lengthwise adjusted to provide for the prop-;,' er height of the die structure after the length of the cutter has. been reduced by grinding off the, same to sharpen. it.

Further objects of the invention are to provide, in a manner .as hereinafter set forth, a diestructure which i s comparatively simple in its construction and arrangement, strong, durable, compact, thoroughlyv efiicient in its use, conveniently lengthei'ied to provide forthe desired height, thereof, and

' readily installedin the machine, as well as I being comparatively 1I1eXP6I1lY9,t0 manufacture. I

lVith the foregoing and other ob e ts in of aacutter 3. The contour'of the cutter 3, is ,of a shapejto conform' to the openings 4 formed .in tlnev piece Ofleather 5,,01: .inpther words the contour. of the cutterfi is shown as .to .providea heelt lift, but they shape of the'v should conform to the contour of, ,the

cutter article. to be cut.

The lower part of the body portion 1; has its inner face cutaway to formashoulder Banda'reduced lower terminalpartT- ,The

of the. part, 7 and abuts against. the. shoulder 4-7. The, cutter 3lis of a height todepend a vsubstantialldistance below the loweredge of :the body portion 1 and further is secured to the latter by any, suitable means. The .loWer ,Qpa-rt of the cutter 3 is. beveled as at 8 and .thejcutting edge ;of thewcutterlis indicated Thetop2 of. the, body portionl, centrally thereof, is. formed ,witha". socket 10-and form-ed inte ral with the top (2 of. the lower section 11, of the ,liandle /and said lower, section .istubular and. forms a continuation of thesoclget 51.0; {the section is formfldgifiltll a lateral opening 12 having the wall thereof snugly engages the inner face of said section 11. The head 14 corresponds in con tour to the contour of the section 11 and is of the same diameter as the outer diameter of said section 11. The head 14 opposes the top edgeiof the section 11. When the section 13 is adjusted a spacing washer or a plurality of spacing washers 17 are interposed between the head 1 1 and the top edge ofzthe section 11 and surround the upper, portion of the shank 15. The section'13 1s maintained in adjusted position by a set V screw 18 having threaded engagement with a Wall ofrthe opening 16 and binding in the groove or cha'nnel16. By the construction aforesaid, when the cutter 3 is ground 'ofi to reduce'the length or height thereof, the

handle can be lengthwise adjusted to providefor the proper height for the die structure.

Referring to Figure 8 of the drawings 18 denotes the body portion ofthe die structure, 19 the cutter and 20 thetop of the body portion 18. The top 20 is not provided with the socket 10 and is solid throughout. The handle comprises a lower section 21 and an upper section 22. The section 21 is solid and further is cylindrical in contour and is formed integral with the top 20 centrally thereof. The upper part of the section 21 is peripherally threaded as at 23." The section 22 is in the form of an interiorly threaded cap nut of appropriate height and whichthreadedly engages with the threads whereby thetw'o sections of the handle are connected together. The manner of "setting up the section 22 with respect to the section 23 provides for the f lengthwise adjusting of the handle to obtain the necessary height for the die structure whenthe cutter 19 has been round' off. A stop nut 24 is carried by the section 21 below the section 22 and which has threaded engagement with the threads 23 of the section 21 and retains theisection 22in adjustedlposition and pre vents the same from riding down on the section 21' when the section 22 has been ada justed.

It isthought the many advantages of a die structure, iu accordance' with this inven- 'tion for the purpose referred to, can be readily understood, and although the preferred embodiment of the inventionis as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall. Within the scope of the invention as claimed.
